selftests: Fix the if conditions of in test_extra_filter() The socket 2 bind the addr in use, bind should fail with EADDRINUSE. So if bind success or errno != EADDRINUSE, testcase should be failed.

selftests/net: remove ARRAY_SIZE define from individual tests ARRAY_SIZE is defined in several selftests. Remove definitions from individual test files and include header file for the define instead. ARRAY_SIZE define is added in a separate patch to prepare for this change. Remove ARRAY_SIZE from net tests and pickup the one defined in kselftest.h.

bpf: fix rlimit in reuseport net selftest Fix two issues in the reuseport_bpf selftests that were reported by Linaro CI: [...] + ./reuseport_bpf ---- IPv4 UDP ---- Testing EBPF mod 10... Reprograming, testing mod 5... ./reuseport_bpf: ebpf error. log: 0: (bf) r6 = r1 1: (20) r0 = *(u32 *)skb[0] 2: (97) r0 %= 10 3: (95) exit processed 4 insns : Operation not permitted + echo FAIL [...] ---- IPv4 TCP ---- Testing EBPF mod 10... ./reuseport_bpf: failed to bind send socket: Address already in use + echo FAIL [...] For the former adjust rlimit since this was the cause of failure for loading the BPF prog, and for the latter add SO_REUSEADDR.

soreuseport: BPF selection functional test for TCP Unfortunately the existing test relied on packet payload in order to map incoming packets to sockets. In order to get this to work with TCP, TCP_FASTOPEN needed to be used. Since the fast open path is slightly different than the standard TCP path, I created a second test which sends to reuseport group members based on receiving cpu core id. This will probably serve as a better real-world example use as well. Signed-off-by: Craig Gallek <kraig@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

soreuseport: pass skb to secondary UDP socket lookup This socket-lookup path did not pass along the skb in question in my original BPF-based socket selection patch. The skb in the udpN_lib_lookup2 path can be used for BPF-based socket selection just like it is in the 'traditional' udpN_lib_lookup path. udpN_lib_lookup2 kicks in when there are greater than 10 sockets in the same hlist slot. Coincidentally, I chose 10 sockets per reuseport group in my functional test, so the lookup2 path was not excersised. This adds an additional set of tests with 20 sockets.

soreuseport: BPF selection functional test This program will build classic and extended BPF programs and validate the socket selection logic when used with SO_ATTACH_REUSEPORT_CBPF and SO_ATTACH_REUSEPORT_EBPF. It also validates the re-programing flow and several edge cases. Signed-off-by: Craig Gallek <kraig@google.com> Acked-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: David S.
